AI Technical Summary
Traditional cloud data management systems are inefficient at handling complex relational queries, making it difficult to provide timely and accurate decision support for emergencies in smart cities.
By constructing an event relationship graph, identifying event primitives and extracting key attributes, a graph matching method is used to efficiently retrieve complex abnormal event chains. Priority identification and hierarchical storage mechanisms are introduced to dynamically monitor and migrate the priority of event primitives and associated edges.
It significantly improves the ability to identify and respond to changes in urban operational status, meeting the "second-level" or even "millisecond-level" response requirements, and providing timely and accurate decision support for smart city management.
